DID YOU KNOW water quality reports, also known as “Consumer Confidence Reports (CCRs),” are annual documents that all public water systems are required to provide to you via mail and online. These reports are supposed to provide important information about the quality of the drinking water delivered over the previous year.
They can be difficult to read or understand. They are often many pages long and contain complex tables and charts. Culligan Water wants to change this and help you MAKE SENSE OF YOUR WATER.
This easy-to-read report will provide you with the following:
- Items of interest: Common water issues discussed within your community.
- Potential concerns: Unregulated contaminants that could be a health concern to you or your family.
The Water Quality Report Legend:
- Health Concern Contaminants that have known health effects that the EPA regulates to protect public health.
- Aesthetic Issue Not necessarily a health risk but can affect your water’s appearance, taste, or odor.
- Unregulated Possible health risk but NO standards set by the EPA. Emerging chemicals and compounds the EPA is gathering data on.
Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water.
Action Level (AL): The concentration of a contaminant that triggers additional action.
Public Health Goal (PHG): The level of a contaminant in drinking water that doesn’t pose a significant risk to health. PHG’s are NOT regulatory standards, and may not be attainable due to current remediation technologies.
ppm: parts per million (μg/L)
ppm: parts per billion (mg/L)
A Summary Of Hudson, NY Water Quality Report
1) Infrastructure & Water System Overview
The City of Hudson operates a public drinking water system serving approximately 5,700 residents through more than 2,200 service connections. During 2025, the system produced approximately 415 million gallons of treated drinking water while continuously monitoring water quality throughout the treatment and distribution process.
Routine testing helps ensure Hudson’s drinking water meets the requirements established by the U.S. Environmental Protection Agency (EPA) and the New York State Department of Health.
2) Water Sources and Usage
Hudson’s drinking water comes from a protected surface water reservoir located in Churchtown, New York. Before reaching customers, the water passes through several treatment processes including:
- Coagulation
- Sedimentation
- Filtration
- Chlorination
- Corrosion control
- pH adjustment
As water travels through lakes, streams, reservoirs, and surrounding watersheds, it can naturally collect minerals and trace contaminants. The City’s treatment process is designed to remove or reduce these substances before the water enters the distribution system.
3) Disinfection and Water Treatment
Hudson uses a multi-stage treatment process to produce safe drinking water.
Recent testing reported:
- Highest Turbidity: 0.33 NTU
- Chlorine Residual: 1.70 ppm
- Haloacetic Acids (HAA5): 30.3 ppb
- Total Trihalomethanes (TTHMs): 43.9 ppb
These disinfectant byproducts are commonly monitored by public water systems and remained below EPA maximum contaminant levels.
4) Water Quality Highlights
Recent testing also reported the following substances:
- Chloride: 40.3 mg/L
- Sodium: 22.5 mg/L
- Chromium: 4.5 µg/L
- Nitrate (as Nitrogen): 0.079 mg/L
- Sulfate: 9.92 mg/L
- pH: 8.07
- Zinc: 0.169 µg/L

Potential Concerns
Explore Unregulated Contaminants in Hudson, New York
Hudson disinfects its drinking water using chlorine to help protect against harmful bacteria and microorganisms. During this treatment process, chlorine can react with naturally occurring organic matter in the source water to form disinfection byproducts such as haloacetic acids (HAA5) and total trihalomethanes (TTHMs).
HAA5
EPA Max. Contaminant Level (MCL): 60 ppb
Public Health Goal: 0
Concerns: Cancer
Removal: Water Softeners, Whole House Water Filters
TTHM
EPA Max. Contaminant Level: 80 ppb
Public Health Goal: 0
Concerns: Cancer
Removal: Whole House Water Filters, Reverse Osmosis Water Filters,
Forever Chemicals
PFAS Contaminants in Hudson, NY
PFAS (per- and polyfluoroalkyl substances), often referred to as “forever chemicals,” have been detected in water supplies across the state of New York. These man-made compounds are valued for their resistance to heat and oil but are slow to break down in the environment. Recent testing reports from Hudson do not report on PFAS in their water supply. However, this does not mean there aren’t PFAS contaminants in Hudson drinking water. Learn more about PFAS and how they enter your home’s drinking water.

Frequently Asked Questions
Is Hudson tap water safe to drink?
Yes. However, this doesn’t mean the municipalities drinking water is clear of any contaminants. Some homeowners often choose additional filtration to help clear their drinking water of contaminants, even at lower levels.
Where does Hudson get its drinking water?
Hudson’s drinking water comes from a protected surface water reservoir located in Churchtown, New York.
Why does my water sometimes taste like chlorine?
Chlorine is added during treatment to disinfect drinking water and protect public health. While safe at regulated levels, some homeowners notice its taste or odor and choose additional filtration to improve drinking water taste.
What are HAA5 and TTHMs?
Haloacetic acids (HAA5) and total trihalomethanes (TTHMs) are disinfectant byproducts that form when chlorine reacts with naturally occurring organic matter during water treatment. These compounds are routinely monitored by public water systems to ensure compliance with EPA standards.
